There were two main arguments over the Northern Whigs:
- Sectionalism: The Northern Whigs were often accused of being too focused on the interests of the North, at the expense of the interests of the South. This led to tensions between the two regions and contributed to the eventual split of the Whig party.
- Compromise: The Northern Whigs were also criticized for being too willing to compromise with the South on the issue of slavery. Some abolitionists felt that the party was not doing enough to fight for the immediate abolition of slavery, while others felt that it was necessary to compromise in order to avoid a civil war.
